Maps for Minecraft PE

Minecraft 0.9.0:

While I wait for Mojang to release the next version of minecraft, I though of a great update that no one has talked about. 

Maps:

Who else agrees that this is small yet important to put into 0.9.0? The next update is apparently supposed to have infinite worlds. The only problem is that there wouldn't be any maps so you don't get lost! Anyway, what do you think? Do we really need maps? And even if infinite worlds don't come around and we're still using the pocket sized world, is it worth it then?
